US 11,229,931 B2 · Apparatus and methods to prevent biofouling

Abstract

Techniques for reducing biofouling on optical equipment, using minimum power in a marine environment are provided. An example apparatus for reducing biofouling in a marine environment includes a housing including a cavity and a convex ultraviolet transparent window disposed over the cavity, an optical device disposed in the cavity and directed towards the convex ultraviolet transparent window, one or more ultraviolet light emitting diodes disposed in the cavity and directed toward the convex ultraviolet transparent window, and a controller operably coupled to the one or more ultraviolet light emitting diodes and configured to provide at least one lamp power function to the one or more ultraviolet light emitting diodes, wherein the at least one lamp power function is based on at least a flash power value, a flash duration, and a rest duration.
